UCD3138RJAR digital power supply controller
The UCD3138RJAR is a high-performance, fully programmable digital power supply controller from Texas Instruments, housed in a 40-VQFN package measuring 6x6 mm, designed for precise control of isolated power conversion in demanding server, telecom, and industrial applications. This device features a 32-bit ARM7TDMI-S core operating at up to 25 MHz, digital control of up to three independent feedback loops with dedicated PID hardware, and operates across the full industrial temperature range of -40°C to 125°C, providing a single-chip solution for complex power topologies.
It distinguishes itself with an array of advanced digital power features, including a configurable nonlinear control engine, a high-resolution error analog-to-digital converter (EADC) with up to 8x oversampling and automatic resolution selection, and up to eight high-resolution digital pulse width modulated (DPWM) outputs with 250-ps pulse width resolution and 4-ns frequency/phase resolution. Key highlights also include hardware-based averaging, a 14-bit effective digital-to-analog converter (DAC) for reference generation, and support for switching frequencies up to 2 MHz, enabling ultra-precise and efficient power supply designs with reduced component count.
Compatible Alternative power supply IC List
● UCD3138RHA: A 40-pin VQFN (RHA) package variant of the same controller with a different pinout or thermal characteristics, offering flexibility in PCB layout and thermal management.
● UCD3138RGC: A 64-pin VQFN (RGC) package variant providing additional I/O pins and potentially enhanced features for more complex control architectures requiring more interfaces.
● UCD3138064: Possibly a different memory configuration or variant within the same UCD3138 family, catering to designs with specific firmware size requirements.
● UCD3138A: An enhanced or later revision of the UCD3138 controller, potentially offering improved performance, additional features, or bug fixes for next-generation designs.
